• pigments are incorporated in a liquid phase in combination with dispersing and wetting agents through the use of energy-intensive ball mills, stirred media mills or high-performance bead mills.
• One way to make the pigmentation of paint systems, printing inks and finishes more efficient and less cost and energy intensive consists in using easily dispersible solid pigment preparations which can be incorporated in the application system with significantly lower energy input and faster color development then conventional pigments, which is of substantial economic advantage.
• WO 2004/046251 describes solid pigment preparations comprising water-soluble anionic additives based on homo- and copolymers of ethylenically unsaturated mono- and/or dicarboxylic acids.

The colorants are isolated after several centrifugation and washing steps.
• pigment preparations with easy dispersibility in both aqueous and solvent-containing application media.
• Such pigment preparations shall be universally compatible and their incorporation shall take place easily and without additional steps irrespective of the application medium.
• Easily dispersible is to be understood as meaning that the pigment is incorporable in the application system with very low energy input and intensive and rapid color development.
• gentle shearing forces for example the action of a dissolver (saw-tooth stirrer), shall be sufficient to achieve complete dispersal of the pigment, removing the need for any further cost-intensive dispersing steps.
